Lyman's Multi-Caliber Ammo Checkers have proven extremely popular with reloaders since their introduction last year. Ammo Checkers are gauges that check the quality and dimensional accuracy of both reloaded and factory ammunition. They are made from solid aluminum and milled with special tools to SAAMI minimum chamber tolerances.
Simply place your cartridge in the gauge and if it fits, then the cartridge will fit in your gun's chamber!

This year Lyman is expanding its Ammo Checkers offering to include additional calibers not included in the multi-caliber blocks.

Each cartridge gauge is clearly marked with the caliber and anodized in a bright orange color.

Suitable for the following calibers:

• 338 Lapua Magnum
